JACK MODELS
BALL SCREW JACKS
ActionJac™ Ball Screw Jacks use a ball screw and nut made from hardened alloy steel with hardened bearing balls carrying the load between nut and screw. This rolling action reduces friction between the nut and the screw permitting smooth and efficient movement of the load. Because of the greater efficiency and rolling action, the ball screw can operate at higher speeds or increased duty cycle when compared with the Machine Screw Jack. The addition of a high efficiency ball screw and nut reduces the required input torque to approximately one-third the torque required for the Machine Screw Jack.
METRIC BALL SCREW JACKS
With over twenty-five years of experience manufacturing precision worm gear screw jacks, Nook Industries has expanded the ActionJac™ offering to include metric models providing design engineers a globally accepted product. All the efficiency advantages that come with ball screw technology are available in ActionJac™ Metric Ball Screw Jacks. A full line of IEC motor mounts are available as well.
MACHINE SCREW JACKS
ActionJac™ Machine Screw Jacks incorporate the use of an Acme Screw with a thread form of 2C. With the use of gear ratios of 20:1 or greater, the jacks can be considered to be self locking. Because the drive sleeve includes the acme thread form, it is possible to have an anti-backlash option.
STAINLESS STEEL SCREW JACKS
ActionJac™ Stainless Steel Machine Screw Jacks are ideal for use in demanding environments where corrosion resistance is required. All external components are manufactured from 300 Series Stainless Steel materials. These jacks use a stainless steel worm with a high strength bronze drive sleeve. Load capacities for Stainless
Steel Machine Screw Jacks range from 1,300 to 23,000 pounds. For increased
capacity, a 17-4PH hardened worm is available.
ActionJac™ Worm Gear Screw Jack systems are ruggedly designed and produced in standard models with load handling capacities from 1⁄4 ton to 100 tons. They may be used individually or in multiple arrangements. There are no “standard” travel lengths and each Worm Gear Screw Jack is built to specification.
The jack housings are made of ductile iron and proportioned to support the rated capacity of the unit. MJ, 1⁄4 ton, and 1⁄2 ton models have aluminum housings.
Each ActionJac™ Worm Gear Screw Jack incorporates an alloy steel worm which drives a high strength bronze worm gear (drive sleeve). The worm shaft is supported on anti-friction tapered roller bearings with external seals provided to prevent loss of lubrication (sealed radial bearings on the MJ, 1⁄4 , 1⁄2, and 1 ton units). The drive sleeve is supported on antifriction tapered roller or ball thrust bearings. Rotation of the drive sleeve causes the lifting screw to translate or rotate, depending upon jack configuration.
CUBIC JACKS
ActionJac™ Cubic Ball Screw and Machine Screw Jacks meet international Cubic Jack versatile mounting standards. Mounting versatility is further increased with the provision for trunnion mounting that is integral to the Cubic Jack housing. Housings are made from high quality, corrosion-resistant aluminum. Cubic Jacks are capable of directly mounting a wide array of motors and gear reducers. Available in true metric and inch execution.
METRIC TRAPEZOIDAL SCREW JACKS
ActionJac™ Trapezoidal Screw Jacks utilize the same rugged design as ActionJac™ Machine Screw Jacks. These true metric jacks include a lift shaft with a special trapezoidal thread form. This thread form has been created to stay within ISO standards yet retains the centralizing feature of our 2C acme threads. These jacks can be supplied with IEC motor mounts.

TRANSLATING JACKSA translating jack has a lifting shaft that moves through the gear box. A nut is integrated with the worm gear such that the worm gear and nut rotate together. When the lift shaft is held to prevent rotation, the lift shaft will move linearly through the gear box to move the load.
JACK CONFIGURATIONSROTATING JACKSA rotating jack has a lift shaft that moves a nut as it turns. The lift shaft is fixed to the worm gear. This causes the load, which is attached to the travel nut, to move along the lift shaft.
In this automobile lift, the linear motion is provided by two inverted rotating ball screw jacks.This printing press application utilizes two upright translating ball screw jacks to set the proper gauge on the feed rollers.

KEYED JACKS The lift shaft of a translating style jack must be attached to something which prevents the lift shaft from rotating. If it is not, the lift shaft (and the load) will turn and not translate. A feature can be added to a machine screw jack to prevent lift shaft rotation. This type of jack is referred to as a “keyed jack” and is available in upright and inverted models. A keyed jack has a keyway machined along the length of the lifting screw. A matching key is fastened to the cover of the jack which will eliminate lift shaft rotation. The keyway in the screw causes greater than normal wear on the internal drive sleeve
threads, somewhat reducing jack life.
Ball screw jacks can also be supplied with a device that prevents rotation of the lift shaft. Anti-rotation is accomplished by a square guide attached to the screw translating inside a square stem cover attached to the jack. The square stem tube is supplied with lube fittings.
DOUBLE CLEVIS JACKS Double Clevis Jacks are used when it is necessary to move a load through an arc, such as tracking antennas, hinged doors or air dampers. Machine Screw and Ball Screw Jacks from 1 ton to 15 ton capacities can be supplied with double clevis mounts. One clevis is mounted on the end of the lift shaft and the other clevis is welded to a heavy duty stem cover, which is welded to the housing. Double clevis designs are available with optional accessories such as boots, motor mounts, right-angle reducers, motors, encoders and rotary limit switches.
To check column strength limitations for each application, use the extended pin-to-pin dimension and the column strength chart on
pages 30 and 68.
NOTE: Mounting hardware for double clevis jacks should be specified as heat treated alloy steel clevis pins with at least 100,000 psi ultimate tensile strength.
Double clevis jacks used horizontally will have reduced column strength and life. For most horizontal applications, Nook recommends the use of an Electric Cylinder (contact Nook Engineering for more information).

ANTI-BACKLASH JACKSAnti-backlash Machine Screw Jacks are used wherever reversible load conditions require precision positioning control. Adjustable backlash Machine Screw Jack models are available to reduce backlash to approximately 0.003”.
An Anti-backlash Machine Screw Jack allows the lash between the drive sleeve thread and the lifting screw thread to be controlled by adjusting the top cover of the jack. The anti-backlash jack design has an upper drive sleeve and a lower drive sleeve. Adjustment of the cover changes the relative distance between the drive sleeves. This change in distance compensates for any lash. Because the drive sleeve is split, the life of an Anti-backlash Machine Screw Jack will be less.
Anti-backlash Machine Screw Jacks minimize backlash, but should not be used to completely eliminate backlash. While it may be desirable to totally eliminate backlash, the result would be a lock-up of lifting shaft and drive sleeve.
Ball Screw Jacks can be factory adjusted to reduce backlash by selecting bearing ball size in the ball nut. This selective fit technique can be used to achieve a lash between the ball nut and ball screw of 0.003” - 0.005”. Precision ball screws with preloaded ball nuts can be supplied to achieve zero lift shaft backlash.
JACK CONFIGURATIONS (CONTINUED)
TRAVEL LENGTH
As a manufacturer of lead screws, Nook Industries stocks a wide selection of inch and metric ball, acme and trapezoid screws in long lengths. Jacks are not preassembled or stocked with standard length screws. Each jack is made to order based on travel length.
Nook Industries has the capability to manufacture long screws for special applications, limited only by the availability of raw materials. Rotating screw jacks may be assembled with a larger diameter lift screw for greater column strength. Jacks can be supplied with special pitch lift screws to change the jack operating speed.
TWIN LEAD SCREWS
Jacks can also be assembled with twin lead screws if required by the application. Contact the engineers at Nook Industries for availability.
TRAVEL VS. INPUT REVOLUTIONS
The number of turns of the worm required to move one inch is a function of the worm gear ratio and the lead of the screw. The charts at the front of each section give the number of “turns of worm for 1” raise” for each jack. The motor rpm divided by this number is the linear speed of the jack lift shaft or travel nut. Conversely, the desired travel rate multiplied by the “turns of worm for 1” raise” equals the input rpm required.
LEAD ACCURACY AND MATCHED LEAD
Lead accuracy is the difference between the actual distance traveled versus the theoretical distance traveled based on lead. For example: A screw with a 0.5 inch lead and ±0.004” per foot lead accuracy rotated 24 times theoretically moves the nut 12 inches. 24 Revolutions × .500 inches per revolution = 12.000 inches of travel.
With a Lead accuracy of ±0.004” per foot, actual travel could be from 11.996 to 12.004 inches.
The rolled thread ball screw, as employed in ActionJac™ products, is held within ±0.004” per foot lead error. The rolled acme thread screws used in our machine screw jacks have a typical lead accuracy of ±0.004” per foot.
When multiple jacks are used to move a load with precise synchronicity, lift shafts of similar lead accuracy can be factory selected and supplied as sets. Consult factory for matched lead set tolerances.
INPUT TORQUE
The input torque is the rotary force required at the input of the jack to generate an output force at the lift shaft. The product specification pages show the torque necessary to raise one pound. This number multiplied by the load is the required input torque.
Due to static friction, starting or “breakaway” torque can be as much as two to three times running torque. If the load is moved horizontally, the force required to move the load will be lessened in proportion to the coefficient of friction of the surface along which the load is moved. In addition, the force needed to start, stop and hold the load (inertia loading) is provided by the jack. Jack sizing should consider all these forces. If an application calls for several jacks to be driven together in series, the first jack should be limited to three times the rated Maximum Input Torque, as listed in the Jack Selection chart for the particular selected jack. For multiple high lead ball screw jacks or belt/chain driven jacks contact Nook Industries for allowable input torque values. Multiple jacks driven in a series may require operation at reduced load.

TARE DRAG TORQUE
The gear box components (bearings, seals and grease) in a jack add “tare drag”. The product specification pages show the tare drag torque. When loading ActionJac™ Worm Gear Screw Jacks with loads less than 25% of their rated capacity, tare drag torque needs to be added to the torque requirement.
INPUT SPEED
ActionJac™ Worm Gear Screw Jacks are rated for up to 3,000 rpm input speed, provided horsepower and temperature ratings are not exceeded. Contact Nook Industries engineers if higher input speeds are required.
DUTY CYCLE
Duty cycle is the ratio of run time to total cycle time. Some of the mechanical energy input to a worm gear screw jack is converted into heat caused by friction. The duty cycle is limited by the ability of the worm gear screw jack to dissipate heat. An increase in temperature can affect the properties of some components resulting in accelerated wear, damage and possible unexpected failure.
Maximum allowable horsepower ratings (see product specification pages) are based on intermittent operation. The approximate allowable duty cycles are: Ball Screw Jacks= 35% Machine Screw Jacks= 25%
SELF-LOCKING AND BRAKES
Self-locking occurs when system efficiencies are low enough that the force on the lifting shaft cannot cause the drive system to reverse direction. Machine Screw Jacks having gear ratios between 20:1 and 32:1, are self-locking and, in the absence of vibration, will
hold loads without backdriving. All other ratios may require a brake to prevent backdriving. All Ball Screw Jacks can backdrive and require some means of holding the load, such as a brake on the motor. The product specification pages show holding torque values. Holding torque represents the amount of input torque required to restrain the load.
In addition to back driving, system inertia usually results in some over travel when the motor is switched off. The inertia of the system should be considered when determining the brake size required to stop a dynamic load.
TEMPERATURE
All ActionJac™ Worm Gear Screw Jacks are suitable for operation within the specified limits provided that the housing temperature is not lower than -20°F or higher than +200°F. Factory supplied grease in standard units will operate in this range. For higher or lower operating temperature ranges contact Nook Industries.
Housing temperature should be monitored and kept below 200°F maximum. Continuous or heavy duty operation is possible by de-rating the jack capacity, external cooling of the unit or through the use of a recirculating lubrication system.
TRAVEL STOPS
Travel stops are not standard. A limit switch and a brake should be used to stop the motor. Mechanical stops can cause damage to the jacks because most electric motors will deliver stall torques much higher than their rated torques and motor inertia can cause severe shock loads. For hand operation, mechanical stops can be provided.
BALL SCREW VS. MACHINE SCREW JACK
The decision to use a ball screw jack or a machine screw jack is based on the application. For many applications, a ball screw model is the best choice. Ball screw jacks are more efficient and therefore require less power than a machine screw jack in the same application.
For low duty cycle applications, for hand-operated applications, or if backdriving is not acceptable consider a machine screw jack.
ActionJac™ Ball Screw Jacks are preferred for:
• Long travel lengths• Long, predictable life• High duty cycles• Oscillating motion
ActionJac™ Machine Screw Jacks are preferred for:
• Resistance to backdriving• Vibration environments• Manual operation• High static loads
JACK SIZING CONSIDERATIONS
Jacks are limited by multiple constraints: load capacity, duty cycle, horsepower, column strength, critical speed, type of guidance, brakemotor size, and ball screw life. To size a screw jack for these constraints, application information must be collected.
LOAD CAPACITY
The load capacity of the jack is limited by the physical constraints of its components (drive sleeve, lift shaft, bearings, etc.). All anticipated loads should be within the rated capacity of the jack. Loads on the jack in most applications include: static loads, dynamic or moving loads, cutting forces or other reaction forces and acceleration/deceleration loads.
For shock loads, the peak load must not exceed the rated capacity of the jack, and an appropriate design factor should be applied that is commensurate with the severity of the shock.
For accidental overloads not anticipated in the design of the system, jacks can sustain the following overload conditions without damage: 10% for dynamic loads, 30% for static loads.
Total Load - The total load includes static loads, dynamic loads and inertia loads from acceleration and deceleration. Also consider reaction forces received from the load such as drilling or cutting forces when using a jack to move a machine tool.
For multiple jack systems, load distribution should be considered. System stiffness, center of gravity, drive shaft windup and lead variation in the lift shafts may result in unequal load distribution. Jacks of varying capacity with equal “turns of worm for 1” travel” may be used to accommodate unequal loading.
Number of Jacks - The number of jacks used depends on physical size and design of the equipment. Stiffness of the equipment structure and guide system will determine the appropriate number of jacks required. Fewer jacks are easier to drive, align and synchronize.
DUTY CYCLE
Cycle Time – Total time the jack is operating in one complete cycle
Duty Cycle – Percentage of time on versus total time.
Verify the duty cycle for the selected jack. Recommended duty cycles at max horsepower are:
• Ball screw jacks = 35% (65% time off)• Machine screw jacks = 25%.(75% time off)
The ability of the jack to dissipate the heat that builds during operation determines duty cycle. Anything that reduces the amount of heat generated or increases heat dissipation will allow higher duty cycles. Jacks may be limited by maximum temperature (200°F) and not duty cycle. Contact Nook Industries for assistance with these applications.
HORSEPOWER RATINGS
The horsepower limit of the jack is a result of the ability to dissipate the heat generated from the inefficiencies of its components. Maximum horsepower ratings are based on intermittent operation. Horsepower is calculated by using the following formula:
The product specification pages show the “torque to raise one pound” value for each jack. Add tare drag torque if operating under 25% rated load.
Horsepower values are influenced by many application specific variables including mounting, environment, duty cycle and lubrication. The best way to determine whether performance is within horsepower limits is to measure the jack temperature. The temperature of the housing near the worm must not exceed 200°F.

For multiple jack arrangements, total horsepower required depends on horsepower per jack, number of jacks, the efficiency of the gear box(es) and the efficiency of the arrangement.

HorsepowerArrangement =

Numberof jacks
GearboxEfficiency
HPper jack
ArrangementEfficiency
N( )
where N = Number of gearboxes.
Do not exceed the maximum allowable input horsepower for a jack. Many models cannot lift the full rated load at 1,800 rpm.
If the horsepower required exceeds the maximum value for the jack selected, several solutions are possible.
• Use a larger jack model to increase the maximum allowable horsepower.• Use a Ball Screw Jack to reduce the power required to do the same work.• Operate at a lower input speed.• Use a right angle reducer to bring the power requirement within acceptable limits.
When utilizing multiple jack arrangements, the input torque to the first jack must be considered. It is recommended that the number of jacks driven through a single jack input be limited to a maximum of three jacks. Consult Nook Application Engineers for arrangements where more than three jacks will be driven through a single jack input.
COLUMN STRENGTH
Column strength is the ability of the lift shaft to hold compressive loads without buckling. With longer screw lengths, column strength can be substantially lower than nominal jack capacity.
If the lift shaft is in tension only, the screw jack travel is limited by the available screw material or by the critical speed of the screw. Refer to the acme screw and ball screw technical sections for critical speed limitations. If there is any possibility for the lift shaft to go into compression, the application should be sized for sufficient column strength.
Charts are provided in each section to determine the required jack size in applications where the lift shaft is loaded in compression.
To use the charts (pages 30, 68, 102, 122, 140, 158, and 159), find a point at which the maximum length “L” intersects the maximum load. Be sure the jack selected is above and to the right of that point.
Maximum Length – The maximum length includes travel, housing length, starting/stopping distance, extra length for boots and length to accommodate attachment of the load.
If column strength is exceeded for the jack selected, consider the following options:
• Change the jack configuration to put the lift shaft in tension• Increase size of jack.• Add a bearing mount (like the EZZE-MOUNT™) for rotating jacks.• Change the lift shaft mounting condition (e.g. from clevis to top plate).
CAUTION: Chart does not include a design factor.
The charts assume proper jack alignment with no bending loads on the screw. Effects from side loading are not included in this chart. Jacks operating horizontally with long lift shafts can experience bending from the weight of the screw.
CRITICAL SPEED
The speed that excites the natural frequency of the screw is referred to as the critical speed. Resonance at the natural frequency of the screw will occur regardless of the screw orientation or configurations of the jack (vertical, horizontal, translating, rotating, etc.). The critical speed will vary with the diameter, unsupported length, end fixity and rpm of the screw. Since critical speed can also be affected by the shaft straightness and assembly alignment, it is recommended that the maximum speed be limited to 80% of the calculated critical speed.
Because of the nature of most screw jack applications, critical speed is often overlooked. However, with longer travels, critical speed should be a major factor in determining the appropriate size jack. Refer to Nook Industries Precision Screw Assemblies Design Guide to best determine the appropriate critical speed for a particular jack selection.
Travel Rate – Establishing a travel rate allows for evaluation of critical speed and horsepower limits. Acceleration/deceleration time needs to be considered when determining maximum required travel rate.
TYPE OF GUIDANCE
Linear motion systems require both thrust and guidance. Jacks are designed to provide thrust only and provide insufficient guidance support. The guidance system must be designed to absorb all loads other than thrust.
Nook Industries can provide either hardened ground round shafting or square profile rail to support and guide linear motion systems.
BRAKEMOTOR SIZING
Safety is the most important consideration. A brake motor is recommended for all ActionJac™ products where there is a possibility of injury.
Only 20:1 or greater ratio Machine Screw Jacks can be considered self-locking in the absence of vibration.
The horsepower requirements determine the size of the motor. Upon selecting a brake motor, verify that the standard brake has sufficient torque to both hold the load and stop the load.
CAUTION: High lead ball screw jacks may require larger nonstandard brakes to stop the load. An appropriately sized brake will insure against excessive “drift” when stopping for both the Ball Screw and Machine Screw Jacks.
BALL SCREW LIFE
A major benefit of the use of ball screw jacks is the ability to predict the theoretical life of the ball screw.
Ball screw life charts are located at the beginning of each ball screw jack section. (pages 28 -29, 121, and 160)

A manufacturer of steel frames used in the commercial dairy industry is building a material lift which contains a stack of prefabricated frames. The material lift will index up as each frame is removed by an automated grip from the top of the stack. The jack will index up 1” in 2 seconds every 30 seconds. After the last frame is removed, the jacks will fully retract to the collapsed position in 6 seconds waiting for the next load of frames. Complete cycle time is 10 minutes running 6 hours per day, 5 days per week. The design calls for a four jack arrangement lifting from underneath the lifting stage, driven by a single motor.
SPECIFICATIONS
• When fully loaded with frames the total weight is 16,800 lbs.• When fully extended the total load is less than 5,000 lbs.• The load will be in compression.• Total travel: 6 inches• Desired design life is one year.ANALYSIS
Configuration: Due to frequent cycles and design life, the use of a ball screw jack would be best suited for this application. Using upright translating jacks will allow the jacks to be located under the material lift and not create any obstruction with the loading and unloading of the prefabricated frames.
Column Strength: The jacks will be fully loaded in the retracted position and be unloaded as they extended. Considering the worst case scenario with the full load at the full extended position, the load will be 16,800 lbs lifted by four jacks, and extended to 6” of travel. When considering column strength, the 2.5-BSJ-U jack can be used.
A leading cookie manufacturer is adding a new product that requires a greater distance to the top heating element of their conveyor oven. The oven originally only had a static-top heating element and with this new order, it needs to be adjustable up to 14 inches. The top heating element weighs 5,000 lb. The manufacturer anticipates only making adjustments to the height once or twice a month.
SPECIFICATIONS
• Single motor and drive.• Food grade grease.• The load will be in compression.• Total travel 14 inches• The actuators and power train must be located outside of the oven frame.• Travel Rate negligible as long as the total travel can be reached in less than 60 seconds.• 2 × safety factorANALYSIS
Configuration: Due to infrequent cycles, the use of a machine screw jack would be best suited for this application. Using upright rotating jacks will allow the jacks to be easily retrofitted to the existing oven with minimal modifications.
Column Strength: The jacks will be fully loaded in both the retracted and extended position. Because of the retrofit condition, it is not possible to have a support bearing on the lift shaft. Using mounting condition A on the Column Strength Chart located on page 68 and the manufacturer’s safety requirements, the 10 ton jack was selected.
Speed and Horsepower: Using a standard 1750 AC Motor and the 24:1 gear ratio, full travel would be reached in 36 seconds. Using the horsepower formulas on page 15 a 5 HP AC motor running at 1750 rpm will be adequate for the requirements.
Line Shafting: The longest center to center distance between any two jacks is 79 inches, leaving a shaft length of 72 inches. Using
Speed and Horsepower: The extension travel rate of 1” in 2 seconds is 30”/min. The retraction travel rate of 6” in 6 seconds equates to 60”/min. This would require using the 6:1 gear ratio when using a 1750 rpm AC motor during retraction and 720 rpm during extension. Using the horsepower formulas on page 15 the total horsepower need when fully loaded is 3.0 HP with a dual speed 1750/800 AC motor.
Line Shafting: The longest center to center distance between any jack and gearbox is 36 inches, leaving a shaft length of 29 inches. Using the formula on page 193 based on Torsional Twist, the proper Line Shafting to use would be the LJ-12.
Life: Based on the indicated cycle rate the total number of cycles over three years is 9,360 cycles. Considering the worst case scenario with the full load to the full extended position, then unloaded for the retraction, the loaded travel inches is just over 56,160 inches. When considering the life expectancy chart on pages 28-29, the 2.5-BSJ-U jack can be used.

A steel tube manufacturer is developing a new OD polisher that will increase production by 22%. Because of the increased production time, the set-up crew is unable to set the feed table manually and is looking to automate the feed table height using screw jack actuators. The feed table length is 24 feet and weighs 5,600 lbs with the largest diameter steel pipe. The table height will need to change approximately once every 15 minutes, but no more than 10 times a day. Maximum height change is 9 inches. The travel rate is .4 inches per second.
SPECIFICATIONS
• Single motor and drive, with the possibility to remove the motor and drive by hand• The load will be in compression.• Total travel 14 inches• .25 inches in 1 secondANALYSIS
Configuration: Because of the possibility to be hand driven, a machine screw jack with 24:1 gear ratio is needed to prevent back driving. Based on the mounting constraints, the upright translating jack with a clevis rod end will be used. Due to the length of the feed table, four jacks will be used in-line with a center mounted motor through a single gearbox.
A manufacturer is looking to periodically raise and lower a cylindrical mixer eight inches during the mixing cycle to allow product testing to insure product quality and consistency. The cylinder weighs 1,700 lbs and is mounting on a movable cart allowing for the final product to be moved to a dispensing station. The customer wants a 4 times safety factor with respect to capacity.
SPECIFICATIONS
• Single motor and drive• The load will be in tension.• Total travel 8 inches• 4 times safety factor• 8 inches in 5 secondsANALYSIS
Configuration: To minimize the size of the motor drive, a Ball Screw jack will be used. Based on the mounting frame, the inverted rotating configurations will be used.
Column Strength: The jacks will be loaded in tension, therefore column strength does not need to be considered
Speed and Horsepower: Using a standard 1750 AC Motor and the 2.5HL-BSJ with the 12:1 gear ratio, full travel would be reached in 3.5 seconds. Using the horsepower formulas on page 15, a 2 HP AC motor running at 1750 rpm will be adequate for the requirements.
LinkJac™Line Shafting: The longest center to center distance between the jack and gearbox is 24 inches, leaving a shaft length of 17 inches. Using the formula on page 193 based on Torsional Twist, the proper Line Shafting to use would be the LJ-8.

Speed and Horsepower: Using a standard 1750 AC motor and the 2.5-MSJ with 12:1 gear ratio, the travel rate will be .6 inches per second. Using the horsepower formula on page 15, the horsepower limit would be exceeded. Using the 5-MSJ 24:1 gear ratio, the travel rate will be .45 inches per second and the horsepower per jack will be sufficient to lift the load. A 3 HP motor would be adequate for the requirements.
LinkJac™Line Shafting: The longest center to center distance between the jack and gearbox is 48 inches, leaving a shaft length of 41 inches. Since the motor is located in the middle, only half the total torque is needed for calculated torsional twist. Using the formula on page 193, the proper Line Shafting to use would be the LJ-16.

BALL SCREW JACKS
Nook ball screw jacks are used extensively in the automobile manufacturing industry.
ActionJac™ Ball Screw Jacks have been designed to produce rated output forces with a minimum amount of input torque. Ball screw jacks use a worm gear set arrangement with an efficient ball screw and nut that reduces the amount of input torque to approximately one-third the torque required for the Machine Screw Jack.
The specifications and data in this publication are believed to be accurate and reliable.

acceptable preferred
OVERTURNING LOAD - A load that tends to rotate the nut radially around the longitudinal axis of the screw. (See FIG. 2)
SIDE LOAD - A load that is applied radially to the nut. (See FIG. 2)
CAUTION: Although a side load will not prevent the ball screw from operating, the nut is not designed to operate with a side load, such as those generated from pulleys, drive belts, misalignment, etc.
THRUST LOAD - A load parallel to and concentric with the axis of the screw. (See FIG. 2)

LIFE - A jack assembly uses rolling elements to carry a load similar to an anti-friction (ball) bearing. These elements do not wear during normal use, but rather fatigue. Therefore, ball screw life is predictable and is determined by calculating the fatigue failure of the components.
Proper lubrication, regular maintenance, and operation within specified limits will allow PowerTrac™ Ball Screws to operate to the predicted life.
BACKLASH - Backlash (lash) is the relative axial movement between a screw and nut without rotation of the screw or nut. The axial movement between a new PowerTrac™ ball nut and screw will range from .003” to .015” depending on size. Lash in ball screws will remain constant during normal use.
SELECTIVE FIT - When less than standard lash (listed above) is desired, ball nuts can be custom-fit to a specific screw with selected bearing balls to minimize lash to .003” to .005” depending on ball size. Select fitting may result in lower life.
LOAD DEFINITIONSCAPACITY - The maximum thrust load – including shock – that can be applied to the ball nut without damaging the assembly.
OPERATING LOAD - The thrust load in pounds which, when applied to the ball nut and rotating screw assembly, will result in a minimum life of 1,000,000 inches of travel. Metric screw designs are per ISO 3408 and show the load ratings in kilonewtons for 1 million revolutions.
TENSION LOAD - A load that tends to “stretch” the screw. (See FIG. 1)
COMPRESSION LOAD - A load that tends to “squeeze” the screw. (See FIG. 1)

1) The recommended maximum speed is 3,000 rpm provided that the recommended horsepower and temperature are not exceeded.
2) Input torque is shown as torque to lift one pound of load. Starting torque is 50% greater than torque shown. For loads less than 25% of rated loads add tare drag torque.
3) Maximum (allowable) horsepower ratings are based on a 35% duty cycle. For operation at higher duty cycles or repeated use over any segment of the total travel, temperature must be monitored and remain less than 200°F.
4) Overload capacity of the Ball Screw Jack is as follows: 10% for dynamic loads, 30% for static loads.
5) All Ball Screw Jacks can backdrive and require some means of holding the load, such as a brake on the motor. The product specification pages show holding torque values. Holding torque represents the amount of input torque required to restrain the load and does not indicate recommended brake size to bring the dynamic load to a stop.
6) All units are suitable for intermittent operation providing that the housing temperature including ambient is not lower than -20°F or higher than +200°F. Factory supplied grease in standard units will operate in this range.
For higher or lower operating temperature ranges consult Nook Industries.

AVAILABLE LIFT SCREW LENGTHS
As a major manufacturer of industrial lead screws, Nook Industries stocks a wide selection of ball screws. Nook Industries has the capacity to make long ball screws for special applications. Rotating
screw jacks can be built with a larger diameter lift screw for greater column strength, or a different lead to change the jack operating speed.
Column strength is the ability of the lift shaft to hold compressive loads without buckling. With longer screw lengths, column strength may be substantially lower than nominal jack capacity.
If the lift shaft is in tension only, the screw jack travel is limited by the available screw material or by the critical speed of the screw. For critical speed limitations, contact Nook Engineering. If there is any possibility for the lift shaft to go into compression, the application should be sized for sufficient column strength.
The chart below is used to determine the required jack size in applications where the lift shaft is loaded in compression.
TO USE THIS CHART:
Find a point at which the maximum length “L” intersects the maximum load. Be sure the jack selected is above and to the right of that point.
CAUTION: chart does not include a design factor.
The chart assumes proper jack alignment with no bending loads on the screw. Effects from side loading are not included in this chart. Jacks operating horizontally with long lift shafts can experience bending from the weight of the screw.

The worm gear driven Machine Screw Jack incorporates an alloy steel worm which drives a high strength bronze worm gear (drive sleeve). The worm shaft is supported on anti-friction tapered roller bearings with external seals provided to prevent loss of lubrication*. The drive sleeve is supported on anti-friction tapered roller or ball thrust bearings. Rotation of the drive sleeve causes the acme thread lifting screw to translate or rotate, depending upon jack configuration.
The jack housing is made of ductile iron** and proportioned to support the rated capacity of the unit. The lifting screw is made of alloy steel with a minimum tensile strength of 95,000 psi. The threads are precision formed, typically using Class 2-C (Centralizing) tolerances. Jack lift shaft lead tolerance is approximately ±0.004”
per foot.

OVERTURNING LOAD - A load that tends to rotate the nut radially around the longitudinal axis of the screw. (See FIG. 2)
SIDE LOAD - A load that is applied radially to the nut. (See FIG. 2)
CAUTION - Although a side load will not prevent the lead screw from operating, the nut is not designed to operate with a side load, such as those generated from pulleys, drive belts, misalignment, etc.
THRUST LOAD - A load parallel to and concentric with the axis of the screw. (See FIG. 2)
Nook Machine Screw Jacks are fitted with Nook’s own PowerAc™ Acme Lead Screws and Nuts. Nook Industries manufactures PowerAc™ precision acme screws by thread rolling for ActionJac™ Worm Gear Machine Screw Jacks, a process that produces high-precision screws. Nook Acme Screw products feature centralizing thread forms for smooth, no-wedging performance.
STRAIGHTNESS - PowerAc™ Acme Lead Screws are straight within .010 inch/foot when shipped from the factory, and do not exceed .030 inch in any 6 foot section.

BACKLASH - Backlash (lash) is the relative axial movement between a screw and nut without rotation of the screw or nut. The axial movement between a new PowerAc™ acme nut and screw will range from .003” to .015” depending on size. Lash in ball screws will remain constant during normal use.
LOAD DEFINITIONSCAPACITY - The maximum thrust load – including shock – that can be applied to the nut without damaging the assembly.
TENSION LOAD - A load that tends to “stretch” the screw. (See FIG. 1)

4) Overload capacity of the Machine Screw Jack is as follows: 10% for dynamic loads, 30% for static loads.
5) Machine Screw Jacks having gear ratios between 20:1 and 32:1 are self-locking and will hold loads without backdriving in the absence of vibrations. All other ratios may require a brake to prevent backdriving.
6) All units are suitable for intermittent operation providing that the housing temperature including ambient is not lower than -20°F or higher than +200°F. Factory supplied grease in standard units will
operate in this range. For higher or lower operating temperature ranges consult Nook Industries, Inc.
7) Accessories such as boots, limit switches, top plates and clevises are available.
8) Catalog dimensions are representative only and are subject to change without notice. For construction, use only certified prints.
9) Units are not to be used as personnel support or movement.
10) End-of-travel stops are not provided.
11) Tare drag torque need only be added if operating under 25% rated load.
12) Starting Torque is 100% greater than torque shown.
13) Measurements listed are for non-keyed jacks. See individual jack pages for keyed jack info.
NOTES:1) The recommended maximum speed is 1,800 rpm provided that the recommended horsepower and temperature are not exceeded.
2) Input torque is shown as torque to lift one pound of load. Starting Torque is 100% greater than torque shown. For loads less than 25% of rated loads add tare drag torque.
3) Maximum allowable horsepower ratings are based on a 25% duty cycle. For operation at higher duty cycles or repeated use over any segment of the total travel, temperature must be monitored and remain less than 200°F.

ActionJac™ Anti-backlash Machine Screw Jacks may be ordered with worm gear sets and lift shafts specifically designed to provide 0.01 inch of travel for each revolution of the input shaft. Referred to as “Numeric Ratio” jack, these units are usually manually operated to precisely position machine components such as end stops or calender rolls.
These jacks can be supplied with handwheels and counters (see ActionJac™ accessories section) to provide immediate positional feedback to an operator. ActionJac™ Numeric Ratio Anti-backlash Machine Screw Jacks retain all the performance characteristics of standard machine screw jacks.

COLUMN STRENGTHMACHINE SCREW JACKS
REFERENCE NUMBER SYSTEMMACHINE SCREW JACKS
Column strength is the ability of the lift shaft to hold compressive loads without buckling. With longer screw lengths, column strength may be substantially lower than nominal jack capacity.
If the lift shaft is in tension only, the screw jack travel is limited by the available screw material or by the critical speed of the screw. Refer to the acme screw technical section for critical speed limitations. If there is any possibility for the lift shaft to go into compression, the application should be sized for sufficient column strength.
The chart below is used to determine the required jack size in applications where the lift shaft is loaded in compression.
To use this chart:
Find a point at which the maximum length “L” intersects the maximum load. Be sure the jack selected is above and to the right of that point.
CAUTION: Chart does not include a design factor.
The chart assumes proper jack alignment with no bending loads on the screw. Effects from side loading are not included in this chart. Jacks operating horizontally with long lift shafts can experience bending from the weight of the screw.
AVAILABLE LIFT SCREW LENGTHSAs a major manufacturer of industrial lead screws, Nook Industries stocks a wide selection of acme screws. Nook Industries has the capacity to make long acme screws for special applications. Rotating
screw jacks can be built with a larger diameter lift screw for greater column strength, or a different lead to change the jack operating speed.

ActionJac™ Stainless Steel Machine Screw Jacks are ideal for use in demanding environments where corrosion resistance is required. All external components are manufactured from 300 series Stainless Steel materials. These jacks use a stainless steel worm with a high strength bronze drive sleeve. The worm and drive sleeve are supported by tapered roller bearings and sealed to prevent loss of lubrication and to resist contamination. The stainless steel lifting screw threads are precision formed to Class 2-C (centralizing) thread profiles.
Load capacities for Stainless Steel Machine Screw Jacks range from 1,300 to 23,000 pounds. A 17-4PH hardened worm is available for a 300% increase in capacity.
STAINLESS STEEL MACHINE SCREW JACKS
Nook stainless steel machine screw jacks are used extensively in the paper industry.

NOTES:1) The recommended maximum speed is 1,800 rpm provided that the recommended horsepower and temperature are not exceeded.
2) Input torque is shown as torque to lift one pound of load. Starting Torque is 100% greater than torque shown. Tare drag torque should be added for all loads.
3) Maximum allowable horsepower ratings are based on a 25% duty cycle. For operation at higher duty cycles or repeated use over any segment of the total travel, temperature must be monitored and remain less than 200°F.
4) Overload capacity of the Stainless Steel Machine Screw Jack is as follows: 10% for dynamic loads, 30% for static loads.
5) Stainless Steel Machine Screw Jacks having gear ratios between 20:1 and 32:1, are self-locking and will hold loads without backdriving in the absence of vibration. All other ratios may require a brake to prevent backdriving.
6) All units are suitable for intermittent operation providing that the housing temperature including ambient is not lower than -20°F. or higher than +200°F. Factory supplied grease in standard units will operate in this range. For higher or lower operating temperature ranges consult Nook Industries.
7) Accessories such as boots, top plates and clevises are available.
8) Catalog dimensions are representative only and are subject to change without notice. For construction, use only certified prints.
9) Units are not to be used as personnel support or movement.
10) End-of-travel stops are not provided.
11) For greater capacity, specify a 17-4PH hardened worm.
12) Tare drag torque need only be added if operating under 25% rated load.
13) Starting Torque is 100% greater than torque shown.

Column strength is the ability of the lift shaft to hold compressive loads without buckling. With longer screw lengths, column strength may be substantially lower than nominal jack capacity.
If the lift shaft is in tension only, the screw jack travel is limited by the available screw material or by the critical speed of the screw. Refer to the acme screw technical section for critical speed limitations. If there is any possibility for the lift shaft to go into compression, the application should be sized for sufficient column strength.
The chart below is used to determine the required jack size in applications where the lift shaft is loaded in compression.
To use this chart:
Find a point at which the maximum length “L” intersects the maximum load. Be sure the jack selected is above and to the right of that point.
CAUTION: Chart does not include a design factor.
The chart assumes proper jack alignment with no bending loads on the screw. Effects from side loading are not included in this chart. Jacks operating horizontally with long lift shafts can experience bending from the weight of the screw.

NOTES:
1) The recommended maximum speed is 3,000 rpm providing that the recommended horsepower and temperature are not exceeded.
2) Input torque is shown as torque to lift one kN of load. Starting torque is 50% greater than torque shown. For loads less than 25% of rated loads add tare drag torque.
3) Maximum allowable horsepower ratings are based on a 35% duty cycle. For operation at higher duty cycles or repeated use over any segment of the total travel, temperature must be monitored and remain less than 95°C.
4) Overload capacity of the Metric Ball Screw Jack is as follows: 0% for dynamic loads, 20% for static loads.
5) All Ball Screw Jacks can backdrive and require some means of holding the load, such as a brake on the motor. The product specification pages show holding torque values. Holding torque represents the amount of input torque required to restrain the load and does not indicate recommended brake size to bring dynamic load to stop.
6) All units are suitable for intermittent operation providing that the housing temperature including ambient is not lower than -30°C. or higher than +95°C. Factory supplied grease in standard units will operate in this range. For higher or lower operating temperature ranges consult Nook Industries.
7) Accessories such as boots, limit switches, top plates and clevises are available.
8) Catalog dimensions are representative only and are subject to change without notice. For construction, use only certified prints.
9) Units are not to be used as personnel support or movement.
10) End-of-travel stops are not provided.
11)ΔStarting torque is100% greater than torque shown.

REFERENCE NUMBER SYSTEMMETRIC BALL SCREW JACKS
Column strength is the ability of the lift shaft to hold compressive loads without buckling. With longer screw lengths, column strength may be substantially lower than nominal jack capacity.
If the lift shaft is in tension only, the screw jack travel is limited by the available screw material or by the critical speed of the screw. Refer to the ball screw technical section for critical speed limitations. If there is any possibility for the lift shaft to go into compression, the application should be sized for sufficient column strength.
The chart below is used to determine the required jack size in applications where the lift shaft is loaded in compression.
To use this chart: Find a point at which the maximum length “L” intersects the maximum load. Be sure the jack selected is above and to the right of that point.
CAUTION: Chart does not include a design factor.
The chart assumes proper jack alignment with no bending loads on the screw. Effects from side loading are not included in this chart. Jacks operating horizontally with long lift shafts can experience bending from the weight of the screw.

NOTES:
1) The recommended maximum speed is 1,800 rpm providing the recommended horsepower and temperature are not exceeded.
2) Input torque is shown as torque to lift one kN of load. Starting torque is 100% greater than torque shown. Forloads less than 25% of rated loads add tare drag torque.
3) Maximum allowable power ratings are based on a 25% duty cycle. For operation at higher duty cycles or repeated use over any segment of the total travel, temperature must be monitored and remain less than 95°C.
4) Overload capacity of the Trapezoidal Screw Jack is as follows: 10% for dynamic loads, 30% for static loads.
5) Trapezoidal Screw Jacks having gear ratios between 20:1 and 32:1, are self-locking and will hold loads without backdriving in the absence of vibrations. All other ratios may require a brake to prevent backdriving.
6) All units are suitable for intermittent operation providing that the housing temperature including ambient is not lower than -30°C. or higher than +95°C. Factory supplied grease in standard units will operate in this range. For higher or lower operating temperature ranges consult Nook Industries.
7) Accessories such as boots, limit switches, top plates and clevises are available.
8) Catalog dimensions are representative only and are subject to change without notice. For construction, use only certified prints.
9) Units are not to be used as personnel support or movement.
10) End-of-travel stops are not provided.
11) Starting torque is100% greater than torque shown.
12) No load torque need only be added if operating under 25% rated load.

REFERENCE NUMBER SYSTEMMETRIC TRAPEZOIDAL SCREW JACKS
Column strength is the ability of the lift shaft to hold compressive loads without buckling. With longer screw lengths, column strength may be substantially lower than nominal jack capacity.
If the lift shaft is in tension only, the screw jack travel is limited by the available screw material or by the critical speed of the screw. Refer to the trapezoidal screw technical section for critical speed limitations. If there is any possibility for the lift shaft to go into compression, the application should be sized for sufficient column strength.
The chart below is used to determine the required jack size in applications where the lift shaft is loaded in compression.
TO USE THIS CHART:
Find a point at which the maximum length “L” intersects the maximum load. Be sure the jack selected is above and to the right of that point.
CAUTION: chart does not include a design factor.
The chart assumes proper jack alignment with no bending loads on the screw. Effects from side loading are not included in this chart. Jacks operating horizontally with long lift shafts can experience bending from the weight of the screw.
AVAILABLE LIFT SCREW LENGTHSAs a major manufacturer of industrial lead screws, Nook Industries stocks a wide selection of trapezoidal screws. Nook Industries has the capacity to make long trapezoidal screws for special applications.
Rotating screw jacks can be built with a larger diameter lift shaft for greater column strength.

operate in this range. For higher or lower operating temperature ranges consult Nook Industries.
7) Accessories such as boots, limit switches, top plates and clevises are available.
8) Catalog dimensions are representative only and are subject to change without notice. For construction, use only certified prints.
9) Units are not to be used as personnel support or movement.
10) End-of-travel stops are not provided.
11) Starting torque is100% greater than torque shown.
12) No load torque need only be added if operating under 25% rated load.

COLUMN STRENGTHCUBIC INCH MACHINE AND BALL SCREW JACKS
COLUMN STRENGTHCUBIC METRIC MACHINE AND BALL SCREW JACKS
AVAILABLE LIFT SCREW LENGTHS
As a major manufacturer of industrial lead screws, Nook Industries stocks a wide selection of screws. Nook Industries has the capacity to make long screws for special applications. Rotating screw jacks can be built with a larger diameter lift screw for greater column strength, or a different lead to change the jack operating speed.
Column strength is the ability of the lift shaft to hold compressive loads without buckling. With longer screw lengths, column strength may be substantially lower than nominal jack capacity.
If the lift shaft is in tension only, the screw jack travel is limited by the available screw material or by the critical speed of the screw. Refer to the ball screw technical section for critical speed limitations. If there is any possibility for the lift shaft to go into compression, the application should be sized for sufficient column strength.
The chart below is used to determine the required jack size in applications where the lift shaft is loaded in compression.
TO USE THESE CHARTS:
Find a point at which the maximum length “L” intersects the maximum load. Be sure the jack selected is above and to the right of that point.
CAUTION: chart does not include a design factor.
The chart assumes proper jack alignment with no bending loads on the screw. Effects from side loading are not included in this chart. Jacks operating horizontally with long lift shafts can experience bending from the weight of the screw.

MOTOR MOUNTS WITH AND WITHOUT BRAKEMOTORS
ActionJac™ Motor Mount assemblies are designed for standard motors and include jaw type couplings. These assemblies are available for the jack sizes listed in the table. Non-standard motor mounts can be designed for special requirements including, special couplings, small NEMA frame motors, DIN standard motors, stepper motor and servomotor designs. See page 190 for Servo Jack motor mount examples, contact Nook Industries for additional information.
ActionJac™ Worm Gear Screw Jacks can be ordered with industrial quality induction motors. Motors with internally and externally wired brake motors are available. Brake motors utilize an integral, spring actuated brake. Standard motors are 3-phase, 230-460 VAC, 60hz, 1,725 rpm. Single-phase motors are 115-130 VAC, 60hz,1,725 rpm. All motors are rated for continuous duty. Specific duty motors such as wash down extended duty may be supplied upon request.
See charts for order codes and motor mount dimensions. Additional motor mounts can be custom manufactured for other jack sizes, please contact Nook Engineering.
CAUTION: Ball Screw Jacks are self-lowering. A brake of sufficient torque is required to hold the load with a ball screw jack. Be sure to verify that the brakemotor selected has sufficient brake torque for your application.

The right angle reducer is a secondary worm gear reducer that reduces speed and increases torque to the input of the jack. If motor clearance is an issue, a right angle reducer may be added to most jacks to optimize motor orientation. Right-Angle Reducers are available in two different styles; High Efficiency and Standard Efficiency.
Right Angle Reducers may be installed on the standard ActionJac™ Machine Screw and Ball Screw Jacks listed below at the time of the order and are available with or without brakemotors.
The High Efficiency Right-Angle Reducer is a compact, high quality worm gear reducer enclosed in an aluminum casted housing. The reducer mounts directly to the input side of the jack. Motors mount quill-style to a standard NEMA C-face. The High Efficiency Right-Angle Reducers are non-vented, oil filled, and maintenance free. They are rated at 85% or greater efficiency - allowing for a smaller drive and motor when compared with standard efficiency right-angle reducers.
High Efficiency Right-Angle Reducers are available in a variety of NEMA motor mounts.
Consult the data charts for jack capacity when a Right-Angle Reducer is used. Ratings given on the chart may differ when a Right-Angle Reducer is installed on Keyed or Anti-Backlash Machine Screw Jack models. Special consideration must be given when installing onto a Double-Clevis Jack due to the additional weight of the reducer.

BRAKEMOTOR REFERENCE
ActionJac™ Worm Gear Screw jacks can be supplied with industrial quality. Brake motors include a spring actuated, electrically released braking mechanism which will hold a load when the power is off. In normal operation, power is applied and removed to the motor windings and brake release simultaneously.
If it is desired to operate the brake separately, as when used with a speed control, the brake needs to be wired externally. Motors provided by Nook Industries can either be supplied with the brake wired externally to accommodate speed controllers, or internally for simplicity of use.
Standard motors are: 3 phase 208-230 / 460 VAC, 60 Hz. 1,725 rpm. Also available are single phase motors at: 115 / 230 VAC, 60 Hz. 1,725 rpm. Standard 3 phase and single phase motors are rated for 50% duty. Wash Down and Explosion Proof motors are rated for continuous duty.
NOTE: for inverter duty motors or additional options, contact Nook Industries.

A handwheel is a convenient solution for manually operating a jack when using machine screw jacks in intermittent positioning applications. Handwheels are available in a range of diameters from 4 to 10 inches and can be adapted for use on jacks from the MJ series up to the 20 ton capacity model.
NOTE: Handwheels do not include a brake and therefore are not for use with ball screw jacks. When using handwheels with a jack that can backdrive (12:1 and lower) an additional locking mechanism may be required to prevent “creep.”

STANDARD MITER GEAR ASSEMBLIES GEAR RATIO 1:1 AND 2:1
Jacks may be used in multiple arrangements by connecting shafting, couplings and gear boxes to simultaneously transmit power to the input shafts of the jacks. Nook Industries provides gearboxes for use with jacks. Make certain that the total torque and horsepower required by the arrangement does not exceed the ratings of the box. For optimum life and noise levels, operate below 900 rpm. Higher speeds are permissible at lower torque ratings. Noise levels may increase at higher speeds. The operating efficiency of a miter gear box is 90%.

HANDBRAKE AS A KIT
CAUTION - Handbrakes are only intended to prevent “creep” due to vibration with machine screw jacks only. They are not designed to be used with ball screw jacks.
Depending on the magnitude of vibration and application life cycles, the handbrake may not be sufficient to secure the load.
Handbrakes are not intended to be used where personal injury could occur.
Handbrake Kits come with Handbrake, Adjustable Handle, two socket head cap screw (SHCS), and two lock washers. To install, remove two adjacent SHCS, and lock washers securing the End Cap. Discard SHCS and lock washers. Clean shaft from any debris or contamination. Slide the Handbrake over the shaft until fully against the End Cap. Install the provided SHCS and lock washers in place of the two that were removed, securing the Handbrake and End Cap in place.

CRITICAL SPEEDThe speed that excites the natural frequency of the screw is referred to as the critical speed.
Since the speed can also be affected by shaft straightness and assembly alignment, it is recommended that the maximum speed be limited to 80% of the calculated critical speed value. The theoretical formula to calculate critical speed in rpm is;
NSpeed = .6192 × ( )2 x Cs
WHERE:
N = Critical Speed in revolutions per minute
L = Length of unsupported shaft in inches
Cs = Value list from table below
Radial support bearings may be needed in order to accommodate the required input rpm. See page 210 - 211 for radial support bearing selection.
π L
TORSIONAL TWIST The degree of twist experienced by LinkJac™ Line Shaft or Tubular Shafting when a given amount of torque is applied. To insure proper synchronization of ActionJac™ motion, it is recommended not to exceed 1° of twist. The theoretical formula to calculate torsional twist in degrees is;
NTwist = T × .
WHERE:
N = Torsional Twist in degrees
L = Length of shaft in inches
Ct = Value list from table below
T = Torque
LINKJAC™ SHAFTING
ActionJac™ LinkJac™ Line Shafting is used to interconnect the input shafts of ActionJac™ Worm Gear Screw Jacks used in a multiple arrangement. The shafts transfer the torque from the motor to the jack or from jack to jack. LinkJac™ is available in either steel Line Shafting available in standard lengths up to 144”, or in aluminum Tubular Shafting with bonded journals of stainless steel available in lengths up to 196”. Custom end machining and other diameters are available. Contact Nook Industries for information.
SELECTION:
There are two major concerns when selecting interconnect shaft:
Critical Speed: How fast will the shaft be turning?
Torsional Twist: How much torque will the shafts be transmitting?
The two characteristics of a LinkJac™ Line Shaft or Tubular Shafting which can be varied to accommodate these requirements are:
• Length of the shaft
• Diameter of the shaft
When selecting a LinkJac™ Line Shaft or Tubular Shafting, use the largest diameter or shortest length which satisfies both of the following equations.
DESIGN INFORMATIONThe length used in the previously listed formulas is the unsupported length of the shaft. If support bearings are used on the shaft, the length is the longest unsupported length between bearings.
The previously listed formulas give a theoretical value of critical speed and torsional twist. Alignment, straightness and stiffness of the system all contribute to determining the actual value.
The torque in the system is also limited by the torque capacity of the coupling.
Allow appropriate spacing between the jack input shaft and the LinkJac™ Line Shaft or Tubular Shafting inside the coupling.
For some combinations of couplings and jacks, the radius of the suggested coupling is larger than the distance from the center of the worm shaft to the base.
Nook Industries offers a range of couplings for use with LinkJac™ Line Shaft or Tubular Shafting and ActionJac™ products in both floating shaft and supported shaft applications. See pages 190-191 for more information.

FLEXIBLE COUPLINGSJacks used alone or in multiple arrangements require couplings to transmit power to the input shaft. Nook Industries provides jaw type and flex type couplings for use with jacks. The selection process for couplings includes the following steps:
1) Refer to the jack specification tables to determine torque requirements per jack for your application.
2) Determine total coupling capacity required by multiplying the torque required per jack by the number of jacks to be driven by the coupling.
3) Check the torque required against maximum torque rating as shown in the table. Select a coupling with a maximum torque greater than the application torque.
4) If using flex type couplings, full-flex couplings should be used for close coupled arrangements. For floating shaft applications, use two
Flex-Rigid couplings. The rigid half should be mounted on the floating shaft.
All jacks, shafts, couplings and motor should be carefully aligned for maximum performance. Couplings with bores other than those specified are available upon request.

CLSH-3 – Standard CLS w. SPDT limit switches, Hall Effect, Pos 3
CLSP-1 – Standard CLS w. SPDT limit switches, Potentiometer, Pos 1
IMPORTANT: These designation numbers are not complete part numbers. These assemblies contain gear reducers with ratios that vary according to the model and travel of the jack. If you are ordering a replacement switch assembly, complete information on the jack is required.
COMPACT LIMIT SWITCH (CLS) PATENT PENDING
Every motorized Worm Gear Screw Jack must be controlled so that power to the motor is turned off and the brake engaged before the limits of mechanical travel are reached. The ActionJac™ Compact Limit Switch (CLS) senses extension shaft rotation and provides switch contact closures that can be used to control motors.
The CLS is an economical way to detect travel limits and prevent over travel of the Worm Gear Screw Jacks. The Single Pole Double Throw (SPDT) limit switches are useful for limiting the maximum and minimum extension.
The CLS is wired as a normally closed circuit, but can easily be wired as a normally open circuit. The CLS is provided with a standard terminal block for ease of set up. The CLS limit switches are adjustable in the field with the removal of the easily accessible enclosure cover.
The CLS is designed to accommodate a variety of standard options, which include a Hall Effect, Potentiometer, and Reed Switch. The potentiometer version is used to provide an analog signal for sensing jack position. The Hall Effect Sensor and Reed Switch are used to provide a pulse signal to indicate jack travel. The CLS has been designed to meet NEMA 4 standards for dust and water tightness. The CLS can be provided with a variety of gear ratios to accommodate virtually any travel.

NOTE: While the 10-turn potentiometer is rated for 10,000 Ohms, as implemented in the compact limit switch assembly, it can not and should not operate over its full range. Minimum and maximum resistance values can not be known until the unit is installed and final travel limit adjustments have been made. Therefore, the device connected to the potentiometer should include provisions for trimming to compensate for these values.

CAUTION: Limit switches are not set at the factory. Switches must be set during installation and prior to use. The limit switch assembly will be permanently damaged if allowed to over travel. CLS is supplied with a plugged access hole. For a water-tight connection, water-tight connector and sealant should be used.
The Compact Limit Switch is not intended to be used as a safety device.

ROTARY LIMIT SWITCH
Every motorized Worm Gear Screw Jack must be controlled so that power to the motor is turned off and the brake engaged before the limits of mechanical travel are reached. The ActionJac™ rotary limit switch senses extension shaft rotation and provides switch contact closures that can be used to control motors.
This sturdy, durable assembly is available with two or four circuits or two circuits and a potentiometer. Each circuit has a separate rotating cam that actuates a high quality switch. The switch actuation may be individually and infinitely adjusted anywhere within the travel of the jack.
These assemblies contain gear reducers with ratios that vary according to the model and travel of the jack. Nook selects ratios that result in maximum cam rotation for best accuracy, repeatability and minimum hysteresis. In most cases, with full travel of the actuator, the cam will rotate 3⁄8 to 7⁄8 of a revolution to actuate a switch. In the event that the cam continues to rotate, the switch returns to its original state after approximately 25° of rotation, with no damage to the limit switch assembly.
The 2-circuit switch assembly is useful for limiting the maximum and minimum extension. The 4-circuit assembly gives the possibility of additional signals for other user purposes. The potentiometer version is used to provide an analog signal for sensing jack position. Single Pole Double Throw (SPDT) switches are standard and Double Pole Double Throw (DPDT) switches are optional. These assemblies are dust protected and meet NEMA 4 and 5 standards for oil and water tightness.
The ActionJac™ rotary limit switch assembly is mounted to the extension shaft side of the ActionJac™ Worm Gear Screw Jack opposite the input.
The rotary limit switch is available for ActionJac™ Worm Gear Screw Jack sizes 2 tons and larger. Most jack models have close and extended mounts to provide clearance around the switch housing. See the following chart for dimensions.
Switches are factory installed to assure proper assembly in the correct orientation for the specified mounting position.

Minimum and maximum resistance values can not be known until the unit is installed and final travel limit adjustments have been made, therefore, the device connected to the potentiometer should include provisions for trimming to compensate for these values.

NOOK SENSOR SYSTEM™ (NSS) PATENT PENDING
The Nook Sensor System (NSS) is designed to meet the need for low cost position sensing on worm-gear screw jacks. It is highly accurate, with repeatability up to ± .004” (0.1MM). The patented design allows users to install and adjust sensors on a single screw jack and integrate easily with a motion control system. Since there is zero maintenance, the Nook Sensor System helps control screw jack systems in ways that have never before been possible.
The sensor system is supplied with two PNP or NPN (normally open) switches. For additional switches or to order a normally closed switch, contact Nook Application Engineers.
HOW TO ORDER THE NOOK SENSOR SYSTEM™
EXAMPLE: 2.5-MSJ-U 6:1 / SSC-1 / SSE-2 / FT / 8 / PS
P = PNP N = NPN
The NSS is designed to allow easy field adjustments. Two magnets are secured to the end of the lift shaft to ensure a positive response once it passes near the position sensor. To adjust the position sensors simply position the lift shaft in the correct position, loosen the locking screw, and then slide the movable sensor to the desired location until the sensor indicates a response. The NSS is supplied with three slots in the stem cover, and two position sensors. Additional sensors can be added or moved to any of the three slots. It is also possible to add multiple sensors to the same slot.

COUNTERS
For precise position display, a range of digital position indicators are available for use with ActionJac™ Worm Gear Screw Jacks. These indicators measure the rotation of the input shaft and display a corresponding position in a counter window. The display value per input shaft revolution is variable and is achieved through a series of gear reductions configured to accommodate different jack ratios, lift shaft leads and travel distances. Contact Nook Industries to determine actual readout scaling available for your application. Not for use with motorized applications. Long travel may result in counter “rollng over.”

CAUTION - Consult Nook Engineering when adding a counter. Some jack configurations may have limited travel.
IN-LINE ENCODER IS INSTALLED BETWEEN THE MOTOR ADAPTER AND MOTOR.
For precise position sensing at the input shaft, an ActionJac™ in-line encoder option may be factory installed between the motor and motor adapter or Right-Angle Reducer. This lowcost option requires minimal space, leaving the extension shaft side of the jack free for clearance, for a rotary limit switch, or for coupling to another jack.
The in-line encoder’s quadrature output design allows detection of both speed and direction of shaft rotation.
The ActionJac™ in-line encoder option requires an optional motor mount or Right-Angle Reducer..
• Sensing speed range: 0 -10,000 rpm
• Pulse output: 60 Pulses per revolution
• Supply voltage: +5 to 24 Volts DC +/-5%
• Supply current: 60 mA typical, 115 mA maximum

The end cuff is designed to fit standard end fittings, the top plate and the clevis end. When jack travel is greater than 6 inches, lift screw closed height increases to accommodate the length of the collapsed boot convolutions. For standard boots the increase in closed height is calculated using the formula shown.
EXAMPLE:BB / 7.50 / 4.00 × 2.0 / 3.00 × 1.50 / 72.00 / G

Boots for upright rotating and inverted rotating jacks are ordered as separate line items. Typical rotating jack applications require two boots, one between the housing and the travel nut and one from the travel nut to the end of the lift shaft. Each boot for a rotating screw jack is ordered as a separate line item. To order boots for a rotating screw jack, select the outside diameter D from the chart on the left and specify cuff dimensions and travel per the diagram using the reference number as shown below. Installation arrangements for rotating worm gear screw jacks vary, therefore boots for rotating jacks must be specified by the customer.

Many applications require longer lift shafts, or jacks that are connected together with a common shaft that is a significant distance apart. Resonance Frequency can cause the lift shaft or link shaft to oscillate and whip, shortening the life of the lift shaft or dislodge the link shafting from its coupling. Radial Support Bearings are used to provide radial support for the lift shaft on rotating style screw jacks, as well as the link shafting products. By adding Radial
RADIAL SUPPORT BEARINGS
Support Bearings, you can increase the effective speed of the lift shaft or link shafting.
There are two styles of Radial support Bearings; Flange Mount and Base Mount. The Flange Mount allows for perpendicular mounting with respect to the axis of rotation. The Base mount allow for in-line mounting with respect to the axis or rotation.

LUBRICATION
ActionJac™ Worm Gear Screw Jacks require lubrication to operate efficiently and with maximum life.
Standard lubrication is NLGI #2 grease. Lubricants are available for both high and low temperature application. If operating conditions exceed 200°F or -20°F, contact Nook Industries for alternative lubricants.
The jack gear boxes are shipped pre-greased unless otherwise specified. Before operating any unit, verify lubricant presence. All jack housings are furnished with a grease fitting and pipe plug.
Lubrication inspection is recommended at regular intervals. Once every six months is satisfactory under normal operating conditions, unless experience indicates that regreasing should occur at shorter or longer intervals. Several operating conditions will shorten the lubrication inspection interval.
Lubricants containing additives such as molydisulfide or graphite should not be used.
Ball Screw models need only a light film of lubricant on the lift shaft for most applications. Nook E-900 Ball Screw Lubricant may be applied with a cloth or spray. Operating a Ball Screw Jack lift shaft without lubrication will result in a ninety percent reduction in life.
Lubrication intervals for the lift shaft of Machine Screw models are determined by the application. Proper lubrication with E-100 spray lube or PAG-1 grease must be provided to achieve satisfactory service life. It is required that screw assemblies are lubricated often enough to maintain a film of lubricant on the screw.
ActionJac™ Worm Gear Screw Jacks are painted with a unique enamel color blend that is specific to Nook Industries. Nook Industries can provide alternative colors and epoxy paints upon request, including specific mil spec paints.
Nook Industries paints are available in 9 oz. aerosol cans in three different colors:

5) Rotate the worms to adjust the timing of the lift shafts as necessary to equally distribute the load. Assemble the load mounting hardware and tighten.
6) Cycle the jacks from closest to farthest point. For rotating jacks with a lift shaft bearing support, loosen the bearing support fasteners and re-tighten to ensure that the lift shaft is parallel to the guide system.
Failure to do this could result in lift shaft stress fracture.
7) Cycle the jacks again and verify that no binding occurs.
Check the lubrication levels, check the limit switch settings (note: rotary limit switches are not factory set), check the tightness of all fasteners and put the jacks in service.
MAINTENANCE
ActionJac™ Worm Gear Screw Jacks require minimum maintenance. In addition to maintaining lubrication levels in the gearbox, the following items should be checked: Lifting screws must be kept free of contaminants and should be lubricated. Refer to the lubrication section on page 212 for appropriate lubrications. If possible, screws should be booted or returned to retracted position when not in use.
For Machine Screw Jacks, lash between the lift shaft and travel nut (or drive sleeve) greater than 1⁄4 the screw pitch indicates the need for replacement of the jack lift shaft drive components.
For Ball Screw Jacks, the ball screw should be checked periodically for spalling of the raceway. In normal operation, ball screw lash does not change significantly over the life of the ball screw.
For all jacks, check the backlash between the worm and worm gear. Lash in excess of 30° for ratios 5:1 to 8:1 and 60° for ratios 20:1 and 32:1 indicates the need to replace the worm and worm gear.
INSTALLATION
Alignment of the jack (or jacks) directly affects service life. Jacks must be properly aligned in all planes so that the main drive shaft can be turned without evidence of binding. The following steps are suggested but may not always be applicable when installing jacks. It is the responsibility of the end user to determine specific installation procedures.
1) The mounting flange of the jack is a precision-machined surface. The worm shaft and lift shaft bearing bores are machined in tight relationship to the mounting flange.
Better mounting surfaces will make it easier to align the jack to the load.
The surface(s) to which the jacks are mounted should be flat, smooth and perpendicular to the guides. Note: for rotating worm gear screw jacks, also ensure that the lift shaft is parallel to the guides.
2) Start with the load temporarily supported in a position closest to the jack housing(s). Locate the jack by putting the jack in place with the fasteners loosely assembled.
3) Level the jacks if necessary. For some applications, a piece of compliant material such as the rubber used for machine isolation bases will help compensate for potential misalignment.
4) Check the level of the load, then, actuate the jacks bringing the lift shaft or travel nut nearly in contact with the load. Adjust the position of the jacks so that the jack attachment points are centered on the load mounting points. Tighten the jack mounting screws. If a compliant material is installed, make sure that the fasteners do not compress the material and that there is clearance around the fasteners.
